Well I have started on my 2nd SID (mono) and have connected the LCD to the core and it works... The one issue I have is that the 2x24 LCD I have requires a 90VAC inverter... Any idea where I can find nfo on this? I checked the board here and found a thread that was to have an attachment for the inverter circuit but it was never posted...

Here is a link to the 2x24 display I am using... http://www.serialwombat.com/parts/lcd107.htm  the link for the inverter on the site is dead...

thanks.

The exact AC voltages for EL on that part (and every EL backlight) are quite relaxed, with 200VAC being the recommended maximum. It's fiddly making an EL driver/inverter circuit. I've had good success using the driver packs from PC EL glow tape mod kits. Same thing.

NOT the Cold Cathode kits (these spew out much higher voltages)

PC Mod kits with either rope/string EL or Tape kits.

I've bought this one recently:

The circuit is potted/encapsulated and has holes for screws/bolts or a sticky pad to mount and two EL connectors...

It works near silently with a 2x40 white EL BL I have for the MB-FM..

Can only hear a slight whine with ear right up to it, which is far better than my own circuit attempts so far.
